城轨车辆制动系统的原理分析.rar

摘  要

   随着城市化进程的加快，越来越多的人们都在寻求更快捷、更环保的出行方式。城市轨道交通由于具有方便快捷、绿色环保等诸多优点，受到了大家的广泛青睐。而城市轨道列车的运营有别于干线铁路车辆，它需要频繁的启动、调速、制动，这就对车辆制动系统的性能提出了更高的要求。

 1）为适应资源节约型和环境友好型社会建设的现实需要，城市轨道车辆所采用的制动系统应尽可能最大的利用电制动，它既能通过能量的回收而产生一定的经济效益，又能减少闸瓦的机械磨耗而降低对环境的影响。 

2）为了适应短距离起停车的特点，必须使列车启动快、 制动距离短。这就要求制动系统装置具有操纵灵活，响应迅速，停车平稳、准确和制动力大等特点。

 3）城市轨道车辆为动、拖车编组列车，所以要求编组列车的各车辆的制动能力尽可能一致，并且能够适应列车乘客量的变化，具有空、重车的调节功能，以降低制动时列车的纵向冲击。 

本论文主要讲述了地铁制动的类型、 地铁车辆及列车制动系统的工作原理和工作过程。并分析了其的优点和不足之处。

 ABSTRACT

With the speeding up of urbanization, more and more people are looking for a more efficient, more environmentally friendly way to travel. Urban rail transit with a convenient, green environmental protection, and many other advantages, is widely favored by everyone. And operation of urban rail train is different from the railway vehicle, it requires frequent start, speed control, brake, it's on the performance of the vehicle brake system put forward higher requirements.

1) in order to meet the reality of the construction of the resource-conserving and environment-friendly society needs, the urban rail vehicles, the maximum braking system should be adopted by the use of electric braking, it can through the energy recycling and produce certain economic benefits, and can reduce the mechanical wear of brake shoe and reduce the impact on the environment.

2）In order to adapt to the characteristics of short on parking, must make the train start fast, short braking distance. This requires a braking device is flexible, quick response and parking steady, accurate, and braking force big, etc.

3) for urban rail vehicle, trailer marshaling, so requires marshaling of each vehicle braking ability as consistent as possible, and the ability to adapt to the changing of the train passengers have empty and heavy vehicle adjust function, in order to reduce braking when the train longitudinal impact.

This paper mainly tells the story of the subway brake type, metro vehicle and train braking system working principle and working process. And analyzes their advantages and disadvantages.

Keywords: subway metro vehicle brake for the wind system and braking system working principle and working process
